Although usually referring to the Northern region of California state, as of 2000, the term bay area was rebranded as an adjective which means gay. This is likely due to the renowned gay population of this region as well as the sexual preference of the man who proudly created this term.

"Bay areaaaaaaaaaaa" = I am gay.
"Yo that is hella bay" = That's gay.
"Bay area chronic!" = I am gay and have smoked good weed in my hometown of San Francisco.

Most commonly refers to the area around the bay located in the northern region of California. The peninsula part is based around San Francisco. The other major areas include Oakland in the east bay, and San Jose in the south bay. The Bay Area constitutes of all those regions and suburbs of those cities near the bay. There are, however, common misconceptions of the bay area, such as the Bay Area of Memphis, Tennessee, as well as a few others. THE BAY AREA MOST COMMONLY REFERS TO THE REGION IN NORTHERN CALIFORNIA, YOU CAN NOT DENY THAT.

The rapper Lil' Wyte states that he is from the Bay Area. He is not from the Bay Area in Northern California, so he is in fact a pussy bitch. E-40 and Too Short are from the Bay Area; Vallejo and Oakland, respectively. Dont hate on the Cali Bay Area just cause your state's Bay Area isnt as well known.

Here's an analogy...When people say Portland (there are 14 Portlands in the U.S.), they're most likely talkin about the one in Oregon.

(my bad if i didnt name your city in the definition of the bay area...i got love for the whole bay...vallejo, concord, richmond, pittsburg, sunnyvale, palo alto (EPA), fremont, mateo, marin, berkeley, and every lil town i forgot from gilroy to sactown to santa rosa and back down)

The San Francisco Bay Area, also known as the Bay Area, is a geographically diverse metropolitan area that surrounds the San Francisco Bay in Northern California. Home to more than eight million people, it is composed of cities, towns, military bases, airports, and associated regional, state, and national parks sprawled over nine counties (ten, according to some agencies) and connected by a massive network of roads, highways, railroads, and commuter rail.
The Bay Area, unlike the typical metropolitan area, contains several distinct urban and suburban centers. While San Jose is the largest city in the Bay Area (having surpassed San Francisco in the 1990 census), for most of its history San Francisco was the largest city in the region. The area containing the city of San Francisco, together with Oakland and San Jose, is the sixth-largest consolidated metropolitan area in the United States.The following lists are based on the ten-county definition of the Bay Area. Cities in bold serve as county seat. The places listed in italics are located in Santa Cruz county, which is excluded by the nine-county definition.
